Error code -29004: This action could not be completed due to possible environment mismatch.

I keep encountering the following error with my Apple ID: Error code -29004: "This action could not be completed due to a possible environment mismatch."

The error occurs after the second request to /GsService2 when submitting the M1 payload. The response I receive looks like this:

<?xml version="1.0" encoding="UTF-8"?>

        </dict>
    </dict>
    <key>Header</key>
    <dict>
    </dict>
</dict>
</plist>

It seems like this error is related to the Apple ID's region and whether 2FA is enabled. For example, US-based accounts work fine, and non-US accounts without 2FA also don't face issues. However, if the account is non-US and 2FA is enabled, this error is triggered.

Any ideas on how to resolve this?
